Floating production platform

Abstract

The invention relates to a floating production platform characterized by comprising a floating body in an octagonal structure. An upper deck is fixedly connected to the top of the floating body; the upper layer deck is provided with an oil gas processing unit and a drilling unit; a through moon pool for drilling work is formed along an axis direction of the floating body; a plurality of first suspension bearers are fixedly and evenly connected to the periphery of the outer wall surface of the lower part of the floating body at intervals; each first suspension bearer is hinged with one end of a steel pipe upwardly vertically arranged via a hinge chain mechanism; the other end of each steel pipe is hinged with a second suspension bearer via a hinge chain mechanism; each second suspension bearer is fixedly hinged to the circumferential edge of a heaving plate horizontally arranged; and through holes with the size equal to the upper layer deck and the heaving plate are formed places of the upper layer deck and the heaving plate corresponding to the moon pool. With the heaving plate hinged under the floating body, floating body heaving range can be effectively reduced and motion performance of the floating production platform can be improved; and the floating production platform possesses functions of deep-draft spar platform, floating production, oil storage and oil discharging devices.

Description

technical field [0001] The invention relates to a floating production platform, which belongs to the technical field of deep water oil and gas field development. Background technique [0002] With the increasing demand for energy in the world and the continuous maturity and perfection of shallow water development technology, the development of deep water has become the development trend of the world's offshore oil. Since the exploration and development of deep-water oil and gas fields is a high-investment and high-risk project, the construction of oil and gas fields must first consider economic benefits. According to the current situation of domestic marine engineering resources, technical equipment and environmental conditions in the South China Sea, my country has proposed the development of a new type of floating production device suitable for the development of deepwater oilfields in the South China Sea. FDPSO (floating drilling, production, storage and offloading unit,...

Problems solved by technology

However, due to the large waterline area of ​​the hull and the limited draft, although it has good stability, its heave performance is difficult to control.

Under operating conditions, the large heave amplitude increases the risk of drilling operations and shortens the operation period, which seriously affects the operation efficiency, and the large heave motion also brings great challenges to the design of the riser
